'Spot The Worm' in Cheeseburger (Viral Photo)

[Updated at 3:30 p.m.] A photo showing an alleged worm found inside a cheeseburger bought from a Davao branch of fast food giant McDonald's has gone viral on Facebook.

A certain Nikki Vea posted the picture on the social networking site Thursday, November 20, with a caption that reads: "Mao ni ang tinuod na picture na burger from MCDONALDS BAJADA na naay WORM. oheeem. SPOT THE WORM! — feeling luod to the max!"

In one of her comments, the uploader said in local dialect that it was her workmate who ate the cheeseburger, adding that they already notified the store management about the extra ingredient, but there was allegedly no action from McDo Bajada.

The photo garnered a few likes and shares on Nikki's account and many more on the Facebook page of Davao City's Public Safety and Security CC/911/TMC Support Group where it was shared Friday morning.

Some commenters said the unwanted burger component looks like an earthworm.
